Scanning tunneling microscopy surface morphology

In addition to surface analytical techniques, microscopy, such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), scanning tunneling microscopy (STM) and atomic force microscopy (AFM), also provide invaluable information regarding the surface morphology, physico-chemical interaction at the fiber-matrix interface region, surface depth profile and concentration of elements. It is beyond the scope of this book to present details of all these microscopic techniques.

The use of high-resolution transmission electron microscopy (HRTEM) and scanning tunneling microscopy (STM) to investigate the morphologies of oxides and chlorides and to compare the surface characteristics of dispersed materials, films, and single crystals. 

In the following the focus will be on the temperature dependence of the surface electronic structure of Gd(OOOl) and Tb(0001) as studied by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS). This dependence is discussed in detail for different morphologies of Gd samples and subsequently compared between Gd and Tb. 

Small molecules capable of forming H-bonds can self-assemble in porous networks [17-19]. Here the porous morphology that is obtained is directed by the H-bonding units present in the molecule. Two-dimensional H-bonded nanoporous networks have been obtained at surfaces and mosdy visualized by scanning tunneling microscopy (STM). Three-dimensional H-bonded nanoporous networks have also been fabricated and analyzed.
